Robert Griesemer f3c39d8f2b go/parser: avoid endless loop in case of internal error 
Factored the error synchronization code into two functions
syncStmt and syncDecl. Because they may return w/o advancing
the scanner, there is potential for endless loops across
multiple parse functions; typically caused by an incorrect
token list in these functions (e.g., adding token.ELSE to
syncStmt will cause the parser to go into an endless loop
for test/syntax/semi7.go without this mechanism). This would
indicate a compiler bug, exposed only in an error situation
for very specific source files. Added a mechanism to force
scanner advance if an endless loop is detected. As a result,
error recovery will be less good in those cases, but the parser
reported a source error already and at least doesn't get stuck.

README 

This is the source code repository for the Go programming language.  

For documentation about how to install and use Go,
visit http://golang.org/ or load doc/install.html in your web browser.

After installing Go, you can view a nicely formatted
doc/install.html by running godoc --http=:6060
and then visiting http://localhost:6060/doc/install.html.

Unless otherwise noted, the Go source files are distributed
under the BSD-style license found in the LICENSE file.

Binary Distribution Notes

If you have just untarred a binary Go distribution, you need to set
the environment variable $GOROOT to the full path of the go
directory (the one containing this README).  You can omit the
variable if you unpack it into /usr/local/go, or if you rebuild
from sources by running all.bash (see doc/install.html).
You should also add the Go binary directory $GOROOT/bin
to your shell's path.

For example, if you extracted the tar file into $HOME/go, you might
put the following in your .profile:

    export GOROOT=$HOME/go
    export PATH=$PATH:$GOROOT/bin

See doc/install.html for more details.
